less和reset.css的引用及首页活动、商品推荐模块的建立及flex布局

?记在前面

          人生最大的希望在于：自己值得自己等待

先打开运行项目：

一、less和reset.css的使用

1.less的引用：

   安装less和less-loader（之前补充过了）传送地址：https://www.cnblogs.com/crystral/p/9117161.html

2.reset.css的引用

①去这个网站（https://cssreset.com/）下载一个reset.css文件，然后copy到src目录下：

（这个我没有下载下来，点击没反应，所以去老师那里copy了一份，代码我放下面）

 reset.css

/**

 ?font-weight: normal;
 ?vertical-align: baseline;
}

/* HTML5 display-role reset for older browsers */
article, aside, details, figcaption, figure,
footer, header, menu, nav, section {
 ?display: block;
}

body {
 ?line-height: 1;
}

blockquote, q {
 ?quotes: none;
}

blockquote:before, blockquote:after,
q:before, q:after {
 ?content: none;
}

table {
 ?border-collapse: collapse;
 ?border-spacing: 0;
}

/* custom */
a {
 ?color: #7e8c8d;
 ?text-decoration: none;
 ?-webkit-backface-visibility: hidden;
}

li {
 ?list-style: none;
}

::-webkit-scrollbar {
 ?width: 5px;
 ?height: 5px;
}

::-webkit-scrollbar-track-piece {
 ?background-color: rgba(0, 0, 0, 0.2);
 ?-webkit-border-radius: 6px;
}

::-webkit-scrollbar-thumb:vertical {
 ?height: 5px;
 ?background-color: rgba(125, 125, 125, 0.7);
 ?-webkit-border-radius: 6px;
}

::-webkit-scrollbar-thumb:horizontal {
 ?width: 5px;
 ?background-color: rgba(125, 125, 125, 0.7);
 ?-webkit-border-radius: 6px;
}

html, body {
 ?width: 100%;
}

body {
 ?-webkit-text-size-adjust: none;
 ?-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}

 ②在App.vue中引入：

③最后，可以去浏览器中看看是不是引用成功了，比如h3块级元素的margin值都为0了

二、新建活动、商品推荐组件

1.进入components文件下，新建活动（active）、商品推荐（recommend）的组件

 2.activity.vue的构建

①template

 ②style

<style lang="less" scoped>
 ?.activity {
 ???background: #eee;
 ???.title {
 ?????width: 100%;
 ?????height: 50px;
 ?????line-height: 50px;
 ?????text-align: center;
 ?????color: gray;
 ?????border-bottom: 1px solid #000;
 ?????background: #fff;
 ???}
 ???.content {
 ?????.content_item {
 ???????background: #fff;
 ???????margin-bottom: 10px;
 ???????img {
 ?????????width: 100%;
 ?????????height: 150px;
 ???????}
 ?????}
 ?????.name {
 ???????font-size: 15px;
 ???????color: #000;
 ???????margin-bottom: 5px;
 ?????}
 ?????.desc {
 ???????font-size: 13px;
 ???????color: #000;
 ?????}
 ???}
 ?}
</style>

 3.recommend.vue的构建

跟activity.vue的结构大同小异，主要是用了一个flex的布局

在这里抛送个阮大神的flex布局的链接：http://www.ruanyifeng.com/blog/2015/07/flex-grammar.html

①template

 ②style

.recommend {
 ???background: #eee;
 ???.title {
 ?????width: 100%;
 ?????height: 50px;
 ?????line-height: 50px;
 ?????text-align: center;
 ?????color: gray;
 ?????border-bottom: 1px solid #000;
 ?????background: #fff;
 ???}
 ???.content {
 ?????display: flex;
 ?????flex-direction: row;
 ?????flex-wrap: wrap;
 ?????justify-content: space-between;
 ?????.content_item {
 ???????background: #fff;
 ???????margin-bottom: 5px;
 ???????width: 200px;
 ???????img {
 ?????????width: 100%;
 ?????????height: 200px;
 ???????}
 ???????.name {
 ?????????padding: 0 5px;
 ?????????font-size: 15px;
 ???????}
 ???????.desc {
 ?????????padding: 0 5px;
 ?????????overflow: hidden;
 ?????????font-size: 13px;
 ?????????.price {
 ???????????color: red;
 ?????????}
 ?????????.price_pre {
 ???????????color: #8e8e8e;
 ???????????text-decoration: line-through;
 ?????????}
 ???????}
 ?????}
 ???}
}

做完以上之后，刷新浏览器是没有反应的，所以看了一下，少了上一节讲的组件的引入

三、看效果
这就是我们首页的活动推荐和商品推荐模块

以上，完成~~~
